The single-component ceramics constituting the composite ceramics used in the present invention, such as serpentine, silica, zinc oxide, tourmaline, zeolite, and calcium oxide, are mixed at preferred mixing ratios shown in Table 3, respectively. Table 4 shows the results of measuring the emissivity, repellency, antibacterial rate, and deodorization rate of the manufactured composite ceramics. Symbols 1 to 4 in Table 4 correspond to symbols 1 to 4 in Table 3.

[0014]

[Table 3]

[0015]

[Table 4]

From the results shown in Table 4 above, all the composite ceramics showed high values in the antibacterial and deodorizing rates due to the synergistic effect of the ceramics of each single component constituting the composite ceramics. It was also found to be excellent in far-infrared radiation characteristics and repellent effect showing insect repellency to sanitary insect pests.

Hereinafter, a method for producing a composite ceramic having antibacterial properties, deodorizing properties and insect repellent properties and far-infrared radiation characteristics employed in the present invention will be described in more detail. The particle size of each ceramic of each single component constituting the composite ceramics needs to use fine powder of 5 μm or less, and when these ceramics are mixed,
Each ceramic has different physical properties such as specific gravity, moisture, humidity, etc., and each of the ceramics as a raw material is a fine powder having a particle size of 5 μm or less. Is not very easy to mix.

The inventor of the present invention introduced the base material, the mixed material and the auxiliary material into the mixer at predetermined ratios according to the preferable mixing ratios shown in Table 3 and mixed and stirred the mixture. To pulverize the mixture, and further, re-pour the pulverized substance into the mixer again, mix and stir, and then repeat the step of successively supplying the pulverized material to the pulverizer for about 30 minutes. As a result, a composite ceramic in which the base material, the mixed material, and the auxiliary material were uniformly mixed could be manufactured.

In order to stabilize the chemical characteristics of the uniformly mixed composite ceramics, the composite ceramics is fired at a calcining temperature of 200 to 500 ° C. by a firing machine to provide antibacterial, deodorizing and insect repellent properties. And a composite ceramic having far-infrared radiation characteristics.

Incidentally, the hydrogen ion concentration of each ceramic which is a material of the composite ceramics is in an alkaline state as shown in Table 5. Also, the composite ceramics composed of each of the above ceramics has an alkaline property as shown in Table 6. Symbols 1 to 4 in Table 6 correspond to symbols 1 to 4 in Table 3.

[0021]

[Table 5]

[0022]

[Table 6]

The hydrogen ion concentration of the composite ceramics employed in the present invention in which each of the ceramics having the hydrogen ion concentration shown in Table 5 is composited is 200 ° C. to 500 ° C. as described above.
Since it is calcined at ° C., as shown in Table 6, it exhibits an extremely stable alkaline property, and the hydrogen ion concentration does not change with time. Further, these composite ceramics are crystallized by calcination to become composite ceramics having a function of generating electric field energy (cation). The reason why the composite ceramic exhibits an alkaline property is that impurities are gasified during the sintering process, so that the composite ceramic becomes more alkaline than a single component ceramic.

From Tables 4 to 6, the composite ceramics obtained by the above-described production method is a composite ceramic having cations, and becomes hydrogen ions in an alkaline region.
It is stable for a long time of not less than one year without change over time, and has a property that the deodorizing mechanism is a decomposing action. As a result, the composite ceramics obtained by the above-described manufacturing method has a far infrared radiation characteristic. In addition, it can be seen that it has both antibacterial property, deodorizing property and insect repellent property.

In general, the surface layer (wall) of living bacteria is an anion, and therefore can only live in the neutral region (pH 7.0 to 7.5). The biggest characteristic of the composite ceramics is that it generates cations as the greatest property, so the surface layer (wall) of bacterial cells that are anions
However, at the same time as being destroyed by the cations of the composite ceramics, the bacterial protein is denatured and becomes difficult to breathe.

Furthermore, the deodorizing effect on hydrogen sulfide and ammonia is not a general effect such as physical adsorption or chemical adsorption, but does not become saturated due to the decomposing effect. It is permanent and has no toxicity.

It is preferable that the particle size of the particles of the composite ceramics used as the material of the production method of the present invention is sufficiently small so as not to hinder the production of rayon. In the case of relatively thick rayon, those having a particle size of about 5 to 15 μm can be used.
Those having a thickness of about 1.5 μm are preferred. Conversely, the particle size is 0.1
When the particle size is less than μm, aggregation of particles is likely to occur, which is often inconvenient.

In the mixing step in the known rayon manufacturing process, the composite ceramics manufactured by the above manufacturing method is put into a mixing machine for mixing to make the quality of viscose constant and uniform. The composite ceramic is added to and mixed with viscose, preferably at a ratio of 5 to 10% by weight, particularly preferably 8% by weight.

Alternatively, instead of adding and mixing in the mixing step of the composite ceramics, after the mixing step and the filtration step,
In the defoaming step of putting the viscose into the spinning tank and defoaming, the composite ceramic is charged into the spinning tank at a ratio of preferably 5 to 10% by weight, particularly preferably 8% by weight. May be added.

After adding and mixing the composite ceramics into the viscose in the above process, rayon is manufactured by a known rayon manufacturing process.

Rayon obtained by adding and mixing the composite ceramics indicated by symbols 1 to 4 in Table 3 obtained with the above particularly preferable mixing ratio to cellulose was tested for antibacterial rate, deodorizing rate, repellent rate and emissivity. However, the results shown in Table 7 were obtained.

[0032]

[Table 7]

Although the composite ceramics used in the production method of the present invention has far-infrared radiation characteristics, the far-infrared radiation of rayon produced by the production method of the present invention and the general-purpose rayon using composite ceramics of different types of ceramics to be mixed. When the emissivity was measured, as shown in FIG. 1, the far-infrared emissivity of rayon according to the production method of the present invention was 5 μm in wavelength.
It was found to be 80% or more over 20 μm from the front and back, which was extremely higher than that of general-purpose rayon. Symbols 1 to 4 in the figure correspond to symbols 1 to 4 in Table 3, and indicate rayon to which each of the composite ceramics manufactured at a preferable mixing ratio is added and mixed. In addition, when the hydrogen ion concentration of each rayon according to the production method of the present invention was measured, each was 7.0 to 7.8 and neutral.

As shown in Table 7 and FIG. 1, the rayon obtained by the method of the present invention has a far-infrared emissivity of 93 to 95%, an antibacterial rate of 89 to 93.5%, and an antibacterial rate of 87 to 95%. It has a deodorizing rate of 95.4%, and has an extremely high repellent rate of 90 to 93% against sanitary pests, and has antibacterial properties, deodorizing properties, insect repellent properties, and far-infrared radiation properties not available in general-purpose rayon. It turns out.

The rayon obtained according to the present invention is mainly used by blending cotton, synthetic fiber and the like, and the proportion of the blend varies depending on the use and the like. The main applications are clothing, kimono, lining, underwear, underwear and blankets.

When underwear and underwear mixed with rayon according to the production method of the present invention having a high far-infrared ray emissivity as described above are worn, the radiation efficiency of far-infrared rays at body temperature increases, thereby increasing the skin surface temperature. In addition, the body water is activated by the radiation of far-infrared rays and the blood flow is promoted, so that there is an effect such as recovery from fatigue. In addition, since the rayon according to the production method of the present invention is neutral at pH 7.0 to 7.8,
Ideal as a material for underwear and underwear to be applied to the human body.

[0037]

The composite ceramics having antibacterial properties, deodorizing properties, and insect repellent properties against sanitary insect pests, which are materials of the production method of the present invention, exhibit alkaline properties, do not change with time in the hydrogen ion concentration, and generate cations. In addition to having the antibacterial properties by killing general viable bacteria, it also has a deodorizing property by decomposing hydrogen sulfide and ammonia, and its antibacterial properties and deodorizing properties have permanent effects. The obtained rayon possesses both antibacterial properties and deodorizing properties by the composite ceramics, and is blended with cotton or synthetic fibers to be used especially for sheets, futon covers and other in hospitals, cloths, socks, etc. The application is extremely wide. Further, since the rayon obtained by the production method of the present invention has a far-infrared radiation characteristic, by using the rayon as underwear or underwear mixed with cotton or the like, the skin surface temperature is raised and the blood flow is promoted. It has the effect of making it work. Furthermore, rayon obtained by the production method of the present invention has a high repellent rate against sanitary pests such as fleas and ticks,
It has an excellent effect that hygiene pests such as mites do not approach and have insect repellency.
